Closed GitFrol closed 1 year ago

Email Provider

ok.de

What happened?

Hi. Noticed interesting behaviour, service faces this error when checking addressed from domain @ok.de. The log is below, I replaced real email address with ***.

Relevant log output

Thanks for the detailed logs. Which version of check-if-email-exists are you using?

GitFrol commented 1 year ago

Sorry, I forgot to mention it. I'm using the latest version of docker image (reacherhq/backend:latest) DIGEST:sha256:9d39357dda465e4dd04baa222b65ab0c90bcae7e6e0fc9461a4278e17d2b0b3c
